I was in the hospital lately for gallbladder surgery and was often being monitored for oxygen saturation which was running between 88 and 92%, with the higher number corresponding to adminstration of oxygen. I didn't realize my levels were that low and understand that 100% is what we would all hope to have.

So now I'm thinking of getting one of those home-use battery-powered oximeters that you clamp on a finger to monitor my oxygen saturation levels.

I've researched these on the web and get mixed conclusion as to whether or not a unit costing between $100 and $200 is worth the money or even if it makes sense for one to be monitoring their oxgen saturation levels in a non-clinical environment.

Anyone use one of these units and have comments on their accuracy or usefullness?
